The old Bouvardia triphylla is a well known favorite, bnt yet not near as common as it deserves to foe. Most cultivators are well aware of its beauty and interest as a pot plant for the greenhouse or conservatory; but few know how ex-cellently it thrives in the open air, in summer, as a border plant. The whole tribe is well adapted to this mode of culture, from B. triphylla to B. leianthe, B. longiflora, and the handsome addition we now afford our readers an illustration of, B. Houtteana. As winter blooming plants for the greenhouse, there are few things superior to the different kinds of Bouvardias, and they are all of the easiest possible culture. They are raised from cuttings of the young wood, but much more easily and rapidly by cuttings of the roots, taken off in February, planted in sandy soil, and kept for a few weeks in a moderate hotbed. The present variety is from the princely establishment of M. Louis Van Houtte, of Ghent (Belgium), and will, we are sure, soon become common.
